In an open channel, the transformation from a supercritical flow into a subcritical flow is a rapidly varied flow with large turbulent fluctuations, intense air entrainment, and substantial energy dissipation called a hydraulic jump. New experiments were conducted to quantify its fluctuating characteristics in terms of free-surface and two-phase flow properties for a wide range of Froude number...

A new method is proposed for simulating the energy dissipation resulting from depth-limited wave breaking, in combination with a universal breaking onset criterion, two-dimensional (2D) fully nonlinear potential flow (FNPF) models, based on non-dimensional strength parameter. Two different 2D-FNPF models are used, which solve Laplace equation Chebyshev polynomial expansions or boundary element ...
